To all whom it may 'concern lle it known that l, RALr'H A. SrANnnY, a citizen vof the United States, residing-'at Gladstone, in the vcounty of Henderson and State of illinois, have inventedV certain new and useful improvements in lnva'lidfBedsteeds, of Which the following is a 's'p'ecrfioaL tion.

The bedstea'd which is the 'subject mattei' of the present application for patient 'is designed more particularly for iil'valids,l and the object' of the invention is to provide a bedstead which is so constructed that the oc# cupant thereof can be readily lifted .or moved about for the purpose of changing the bedding or other parts, and attending to the wantsof the occupant. I

The in'vention also has for its object to provide a bedstead which is perfectly sanitary, and also simple and cheap in construc-A tion.

Other objects and advantages Will"be pointed out in the detailed description appeering hereinafter, and in order that the invention may be better understood, reference is had to the accompanying drawings, in Wliiclr- Figure 1 is a plan vievv of the bed'stead,

partly broken away and in section; Fig. 2 isa cross-section on the line 2-'2 of Fig. 1; Fig". 3 partly broken away'A and in sectioilglFig'. 4: is a horizontal sec ion on the line 4 4 of Fig. 3; Fig. 5 is a. crass-section of the bed- Stead on the une 5f5 or Fig. i, and Figs. 6 and 7 are sectional details ori the lilies 6-6 and 7 7, respectively, f Fig; 1.

Referring specifically to the drawing the bedstead proper comprises head and foot sections 10 and 11-7 respectively, and side rails 12 connecting the same. rlhe head sctionhas a top cross bar 13, and the foot section a top cross bar 14;. This structure is mounted on a pedestal comprising a sta'- oor, and a hollow plunger 1G Working in said cylinder and carryingT the bedste'ad, which latter' is adapt-ed to be' raised or lowered by sliding the plunger in thc cylinder; The top of the plunger is closed by a plate 17 at the center of which is a bearing 18 in which is stepped a pivot 19 extending downward from the bottom of a plate 2O secured to and connecting the rails 12. The bedstead is thus svvlvelcd to the plunger and it may is a side elevation of the beds'te'ad be 'svvung around in a horizontal plane to facilitate access to either side thereof. The plate 17 carries anti-friction rollers 21 which engage the under side of the plate 20.

The plunger 16 is operated to raise or loafer the bedstead, by means of a non-travel i'ng 'screiv` 22 supported in upright positionv by a cross bai- 22'EL mounted in the` cylinder 'and threaded through a nut 23 vat the Vcenter of a spider 24 secured inside the pluri'- 'geiz' 'screw is actuated by a gearing comprising a bevel gear 25 in mesh with a similar geaf 26 on the lovver end of the screw. The gear is on a shaft 27 journaled in the `v'v'all vof the 'cylinder and having at one end, on the outside of the cylinder, a hand- Wheel 28, 'and a paWl-and-ratchet mecha'- nism 29 lfor pre've'r'iti'nigfJ the shaft from slip- ,ping. rThe Wall of the plunger has slots 30 to accommodate the cross bar 22, these 'l parts also serving to preventJl the plunger yfrom rotatingY in the cylindeVA The plate 17 is circular and has notches @31 in vits peripheryengageable by locking dogs 32 carried by the plate 20, whereby the Ibedstea'd may be locked afte'r it is 'swung 'around to the desired position.

On the corner posts of the head and foot sections 10 and 11v is slidably munt'ed'a lift- .,ing or carrier frame composed of side rails and end 'rails 34 connecting the sanie. At the junction of the rails aie socket pieces Ehlegh whiehth corner posts pass, Whefe- @by the frame' is s idably supported by said posts so that it may be raised di lv've'red.

i I inside the lifting frame is heid stretched a fishe'et 36'f canvas' or other suitable strong imaterial, said sheet beir'ig1 secured at its lou-4 1' 1itudinal ed es to rollers 37 journaled in 4t e end rails 4:. To the endsof the rollers are attached 'crank-handles 3s for raming the former to Wind the 'sheet thereon and tlilS keep the Siil tightly Stlllclid. PaWl? 'and-ratchet devices 39 are provide'dto prevent the rollers from slipping;y lin the sheet is a hole 110 for a vessel.

The following means are provided fo'i raising and loweringL the lifting frame: @n the top cross bars 1B are mounted sheaves 41 over which pass hoisting lines 42. To the end rails 34 arean'chored coiled springs 48; The lines ll2 pass downward from the sheaves and are connected at one of their ends to the springs. The other ends of the lines extend downward to the pulleys t lll@ mounted on cross rails connecting the corner posts otI the head and foot sections 0f the bedstead. After passing over the lastmentioned pulleys, the lines are carried forward toward the middle of the bedstead and wound 0n rollers 46 extending transversely between and supported by the side rails 1iof the bedstead. These rails also support a transverse shaft 47 which is geared at 48 to the -rollers 46 so that when said shaft is rotated, both rollers are rotated to wind up or pay out the lines 42. Both ends of the lifting frame arev therefore elevated or lowered uniformly and said frame is kept level. hand wheel 49 for operating the same, and a pawl-and-ratchet device 50 for preventing the shaft from slipping is also provided,

By means of the springs 43 the lifting frame is spring-supported and the patient is not jarred when said frame is elevated or lowered.

The lift-ing frame also carries a head rest which is adjustable lengthwise of said frame so that the patient may be brought back if there is a tendency for the patient to slip down in the bed. This head rest comprises a slidable frame having side rails 51 which are angular in cross-section so that they may be mounted on the side rails 33 of the lifting frame. which travel along the top and bottom cdgcs of the rails 33. The head ends of the rails 51 are connected by a cross-rail 53. At the head end of the side rails 51, the top flanges thereof have apertures 54 into selected ones of which are adaptedto be inserted upwardly curved resilient strips 55 connected at their upper ends by a cross-rod 56. The head rest frame is covered by a sheet 57 which also extends between the strips 55 and up to the cross-rod 56, the side rails 51 and the strips 55 having buttons or other suitable fasteners 58 by which the sheet is removably secured.

As the strips,55 are resilient they may be swung up or downfto raise or lower that` part of the sheet which extends therebetween. The strips may also be adjusted lengthwise of the side rails 51, a series of apertures 54 being provided for this purpose. The tendency of the strips 55 is to spring upward, and they are held in adj usted position by a strap 59 connecting the cross-rail 53 and the cross rod 56.

In order to pull the head rest frame along the side rails 33 of the lifting frame toward the head end of the latter, hauling lines 60 are connected to the cross rail 53 and wound on a roller 61 supported by the end rails 34, the ends of the roller being equipped with crank handles 62 for operating the same. Thus, if the patient slips down toward the On each end of the shaft 47 is a' The side rails 51 carry rollers 52- foot of the bedstead, he can brought back.

I claim:

1. The combination of a cylindrical pedestal, a hollow plunger slidably mounted in the pedestal, a top plate carried by the plunger, a bedst-ead swiveled to the top plate be readily ,to swing in a horizontal plane, a cross-bar versely between the side rails, aroun which rollers the hoisting lines are wound, guide pulleys adjacent to the ends of the side rails over which guide pulleys the hoisting linesv pass to the rollers, and means for operating the rollers.

3. The combination with a bedstead having side'rails, corner posts and top cross rails connecting the'corner posts, of a lifting frame slidably mounted on the corner posts, sheaves carried by .the cross rails, hoisting lines passing over the sheaves, resilient, connections between the hoisting lines and the lifting frame, rollers extending transversely between the side rails, around which rollers the hoisting lines are wound, guide pulleys adjacent to the ends of the side rails over which guide pulleys the hoist ing lines pass to the rollers, and means for operating the rollers,

4. The combination with a bedstead having corner posts, of a lifting frame slidably mounted on said posts, raising and lowering means for the frame, rollers carried by the frame on opposite sides thereof, a sheet wound on the rollers, and means for opcrat- .ing said rollers.

5. In a bedstead, a head rest frame having side rails, supporting side rails on which the side rails of the head rest frame are slidably mounted, and a hauling device connected to the head rest.

6. In a bedstead, a head rest frame and having side rails provided with apertures, resilient upwardly extending strips seating in the apertures, means for holding the strips, and a covering between the side rails and the strips. Y

In testimony whereof I affix my signature in presence of two witnesses.
